drm/nouveau: fix bogus GPL-2 license header The bulk SPDX addition made all these files into GPL-2.0 licensed files. However the remainder of the project is MIT-licensed, these files (primarily header files) were simply missing the boiler plate and got caught up in the global update.

drm/nouveau/bios: namespace + nvidia gpu names (no binary change) The namespace of NVKM is being changed to nvkm_ instead of nouveau_, which will be used for the DRM part of the driver. This is being done in order to make it very clear as to what part of the driver a given symbol belongs to, and as a minor step towards splitting the DRM driver out to be able to stand on its own (for virt). Because there's already a large amount of churn here anyway, this is as good a time as any to also switch to NVIDIA's device and chipset naming to ease collaboration with them. A comparison of objdump disassemblies proves no code changes. Signed-off-by: Ben Skeggs <bskeggs@redhat.com> 2015-01-14 14:40:03 +10:00			`bmp_version(struct nvkm_bios *bios)`
